Giving the immune system a double boost against cancer

Researchers have developed a new treatment that induces an integrated immune response in tumors of patients with pancreatic and colorectal cancers, which are resistant to immunotherapy. The treatment, plerixafor, works by interrupting an immunosuppressive pathway, allowing critical immune cells to infiltrate the tumors.

New artificial skin functions like natural skin

Researchers created an artificial skin equivalent that reproduces traction-force balance in the lateral direction, a property controlling skin structure and function. This human-skin equivalent enhances physiological skin function analysis, disease research, and reduces animal testing.

Asteroid's scars tell stories of its past

Researchers studied impact marks on asteroid Bennu to reconstruct its history, revealing it formed hundreds of millions of years ago but wandered into Earth's neighborhood recently. The study provides a new benchmark for understanding asteroids and offers insights into hazardous space debris.

Well oriented

Researchers at the University of Tokyo have developed new palladium catalysts for polymerization, enabling the efficient synthesis of isotactic polar polypropylene (iPPP) with high isotacticity. The discovery opens up new possibilities for creating specialty plastics with improved wettability or enhanced degradability.

How octopus suckers "taste by touch"

Researchers have discovered how octopuses can taste objects by touch using their suckers, which include discrete populations of sensory cells. The study found that distinct chemotactile receptors form ion channel complexes that detect specific signals and send them to the nervous system.

Autoantibody order, timing predict genetically at-risk children most likely to get T1D

Children with multiple islet autoantibodies are more likely to progress to symptomatic type 1 diabetes than those who remain positive for a single autoantibody. Detailed information about the order, timing and type of autoantibodies appearing after the first autoantibody can significantly improve prediction of which children are most l...

New study demonstrates importance of large-scale SARS-CoV-2 antibody

A novel approach to measuring antibodies against SARS-CoV-2 has been developed, revealing a discrepancy between reported virus-positive cases and actual antibody prevalence. The study found that over 47% of antibody-positive children were asymptomatic, with significant geographic differences in antibody frequency across Bavaria.

Why people with dementia go missing

A new study from University of East Anglia found that people with dementia are at higher risk of going missing in areas with dense and disordered road networks. The research identified environmental risk factors that contribute to the issue, including complex intersections and disorganized layout.

New assay screens human brain organoids, doubles known candidate genes for microcephaly

A new tissue screening assay for human cerebral organoids identified 25 additional candidate genes for microcephaly, nearly doubling the number of currently known genes linked to the rare neurological condition. The CRISPR-LICHT technology revealed these genes associated with both known and previously unknown microcephaly-driving pathw...

Where were Jupiter and Saturn born?

A team of scientists, led by Matt Clement, used simulations to study the formation of Jupiter and Saturn. The findings suggest that these two planets were originally closer together than previously thought, with a ratio of two Jupiter orbits to one Saturnian orbit being more consistent with the current configuration.

Asteroid Ryugu shaken by Hayabusa2's impactor

The Hayabusa2 mission's artificial impact crater on asteroid Ryugu revealed significant boulder movements and seismic shaking, up to 40m from the center. The study provides valuable insights into asteroids' resurfacing processes and can be used as a benchmark for numerical simulations.

Brainstem neurons control both behaviour and misbehaviour

A recent study at the University of Helsinki found that brainstem neurons play a crucial role in controlling both normal behaviour and misbehaviour in mice. The researchers discovered that faulty gene regulation can lead to behavioural abnormalities such as hyperactivity and attention deficit. The study provides new insights into the d...

Touch and taste? It's all in the tentacles

Researchers at Harvard University discovered a unique sensor system in octopus suction cups that allows them to detect and 'taste' molecules on objects, enabling the animals to identify prey. This novel chemotactile receptor system may also facilitate complex behaviors in octopuses and other cephalopods.

Flash graphene rocks strategy for plastic waste

Researchers at Rice University have created a new method to convert plastic waste into high-quality graphene, offering a potential solution to the global plastic waste crisis. The flash graphene process eliminates much of the expense associated with recycling plastic, making it an economically viable alternative.
